Hi,
I'd like some advice on which format to use for transmitting data over TCP. Currently, I have devised a simple text-protocol with delimited strings. I'm thinking I should use something out there that already exists such as XML, JSON, or XMPP?
What...

It is only when you have more complicated needs that you have to do anything more fancy than that .
In most cases folks just declare a record with a layout that is reproducable on both ends and use that .

A valid JSON Syntax is something of the kind:
{ "username" : "admin", "password" : "123" }
But what if I want to transmit an array of 'users' ( given the example ), instead of a single 'user' ?
Is the code below Valid JSON, according to the specifications...

It’s extremely simple to understand, IMHO.
The not-very-well-known page json.org has a diagram that shows the syntax .
Edit : Here is a good link on JSON and its usage .
Yes, your example is valid JSON - that is exactly how you want to use an array .

Are you transmitting a buffer or a string? If you transmit a string specify how many bytes you want to transmit and include the null character.
Is on the sending or the receiving end.

A teacher is writing on a blackboard and we want to pass all the information on the blackboard over a low-bandwidth network in real-time. How do we do it?
In one interview, I faced this question.

To do it, if you have that sort of blackboard, is to transmit a pair of x,y coordinates of the points.

It depends upon the sort of data that you're sending, but if you're using serialization to create the data, then serializing to XML and compressing that with a GZipStream can result in fewer bytes than compressing the data generated by a binary serialization... .

I'm looking for a forward error-correcting code that is relatively easy/fast to encode on a microcontroller; decode will be done on a PC so it can be more complicated.
I don't know that much about error-correcting codes and except for the simple Hamming...

Thus, my recommendation would be instead to divide your data streams up into blocks (1 KB, ... .
The problem with error correcting codes is that they'll let you recover from single bit or maybe 2 bit errors, but usually not detect or patch up major damage .

You need to build a better transmitter.
